Dear Mathieu ,
Thanks for your valuable answer. I managed to install memcached and
its extension in ubuntu and caching is working fine. My following code
is working fine.
[syntax=php]<?php
error_reporting(-1);
ini_set('display_errors', true);
$memcache = new Memcache();
//$memcache->connect("10.1.11.33",11211) or die ("Could not
connect");
$memcache->addServer("10.1.11.33",11211, 33);
echo "version = " . print_r($memcache->getVersion());
if ( ! extension_loaded('memcache')) {
throw new Doctrine_Cache_Exception('In order to use
Memcache driver, the memcache extension must be loaded.');
}
?>[/syntax]
And from symfony I used resultcaching. It is also working. I verified
by modifying the content in the database and the modified content is
not loading in the result. But after the life span the changed content
is loading.
Here is the code snippet which I used to load the cache driver in the
symfony framwork.
[syntax=php] public function configureDoctrine(Doctrine_Manager
$manager) {
$servers = array(
'host' => '10.1.11.33',
'port' => 11211,
'persistent' => true
);
$cacheDriver = new Doctrine_Cache_Memcache(array(
'servers' => $servers,
'compression' => false
)
);
//enable Doctrine cache
$manager = Doctrine_Manager::getInstance();
$manager->setAttribute(Doctrine::ATTR_RESULT_CACHE,
$cacheDriver);
$manager->setAttribute(Doctrine::ATTR_RESULT_CACHE_LIFESPAN,
900);
}[/syntax]
But I have one more issue. When I tried to clear the cache it is
giving me the an error [quote]In order to use Memcache driver, the
memcache extension must be loaded.[/quote]
But in the sample code this error is not returning.
Do u have any solutions for this?
regards
Shihab
